Post Processing Data Collection
Data collection for post processing involves storing GPS raw
data to a file on disk. The file is usually stored on the
receiver’s internal memory, but for certain brands and
models, you can also store the data to a file on the data
collector. Raw data from multiple receivers is combined and
then PC software is used to process the base line
measurements. This section describes:
¾ How to open a data file and start recording GPS raw
data for post processing.
¾ How to start and stop static (fast static) as well as
stop and go data collection.
¾ What to do with the data.
Note: If you wish to log post processing data simultaneous
with RTK data collection, please see the previous section.
Post Processing Receiver and Settings
To do post processing data collection, you must first create a
post processing receiver profile. Please see the first section
for a description of the Receiver Setup screen. You then need
to make sure recording is turned on. Go to the Job | Settings
| Post Process screen and check the Recording Interval is not
set to Off. You can also use this screen to select a special
layer for post processing points, and to turn on the Session
Monitor to warn you if data collection criteria is exceeded
during post processing sessions.
Start Receiver Recording
To open a data file and begin logging GPS raw data, go to the
Survey | Post Processing screen. Choose to start a Static post
processing file if you intend to leave the receiver stationary
over a point for the entire session. Choose to start a Stop and
Go
post processing file if you intend to move around with the
receiver and stop on data collection points.
Measure the antenna height and tap Start Recording. If you
start a static file, the Static Receiver Session screen is opened
